Definitions
- the present invention relates to frames for lifting and placement of seabed mats and particularly to concrete seabed mats.
- seabed mats are stacked upon each other, several layers high.
- the lifting and placement device is then maneuvered to the top mat. Climbing up on these stacked mats to connect the lifting device to the mat presents a dangerous situation when working in a wet and turbulent environment such as a boat in the middle of the ocean or other large body of water. Therefore, there is a need for a lifting and placement device for seabed mats that allow for a safe and easy way to connect the mat to the lifting device, without endangering the individual performing the task.
- the present invention provide a lifting and placement device for concrete seabed mats having a frame for supporting the mats and a release mechanism which adequately supports the mats on opposite sides of the frame and which proves stable when supporting the heavy material.
- the present invention further provides for a lifting and placement device for seabed mats which has an actuation lever and in which the design allows for multiple lifting devices to be placed in end to end relationship.
- FIG. 1 is a perspective view of the device of the present invention
- FIG. 2 is a perspective view of the device of the present invention supporting a concrete pad
- FIG. 3 is a close-up perspective view of the locking device for the actuation lever found on the device in FIG. 1;
- FIG. 4 is a close up of the support and release mechanism for the device of FIG. 1;
- FIG. 5 is a close up of the support and release mechanism for the device of FIG. 1;
- FIG. 6 is a perspective view of the device of the present invention wherein multiple frames are adjoined.
- the seabed placement device 10 of the present invention is depicted in FIG. 1 .
- the placement device 10 of the present invention provides for direct and concise placement of seabed mat 70 in an underwater environment or in other areas.
- the seabed mat placement device 10 of the present invention fully supports the seabed mat until release of the mat by movement of actuation lever 36 .
- the placement device 10 of the present invention may be supported by a crane or other device through support chains 50 which may be raised after the placement device 10 is fully connected to a mat 70 .
- the placement device 10 of the present invention allows for the accurate placement of a mat by activation of a single actuation lever 36 which immediately releases all retaining mechanisms supporting the mat 70 below the placement device 10 .
- the placement device 10 of the present invention allows the mat 70 to be placed in the proper position and then accurately released on all sides in a single movement. Release of the mat 70 from the placement device 10 may be effectuated by simple rotation of an actuation lever 36 located at a far end of the placement device 10 . Rotation of the actuation lever 36 will automatically release all supporting pins 44 which retain the seabed mat 70 through use of the mat support lines 72 and support straps 57 . Thus, automatic and full release of the supported seabed mat 70 may be completed from an adjacent or remote location and not necessarily from an area directly on top of or associated directly on the actuation shaft 30 which is centrally aligned on the placement device 10 . Further, the retaining pins holding the mat 70 are located directly above the supported area of the mat thereby ensuring accurate placement of mat 70 .
- the placement device 10 of the present invention will support a seabed mat 70 which may contain a plurality of cement blocks 73 .
- the plurality of blocks 73 may be conjoined in a rectangular shape to form a large mat as is depicted in FIG. 2, all of the blocks attached together longitudinally and laterally by mat support lines 72 and 75 .
- each of the individual blocks 73 may receive support lines in perpendicular fashion in order to increase the strength of the seabed mat 70 and allow the entire seabed mat to be raised and lowered by the support lines 72 and 75 .
- the blocks may be designed in hollow form as is depicted in order to form an open cell 76 which thereby reduces the weight of the entirety of the seabed mat 70 .
- the typical mat may be approximately 20 by 80 feet and the placement device 10 of the present invention may be sized to fully support such mat.
- a preferential mat for utilization with the placement device 10 of the present invention may be found in co-pending U.S. patent application Ser. No. 09/563,171 which is incorporated herein by reference.
- the placement device 10 of the present invention may be utilized in combination with a significant number of devices which require supporting and immediate release from a supporting platform.
- the seabed mat placement device 10 of the present invention may not be so construed as to be limited for use in conjunction with the seabed mat described herein and one of ordinary skill in the art may interchangeably utilize a significant number of objects which require support and release.
- the mat 70 may be supported by the placement device 10 through the use of a plurality of support straps 57 which wrap around the open loop ends of the block support lines 72 .
- the support straps 57 have a first and a second end, the first end 55 being looped around a retaining pin 59 , shown in FIG. 4, while the opposite loop end 56 of the support strap 57 may be retained in place by a displaceable supporting pins 44 .
- the displaceable supporting pins 44 pivotally engage a support bracket 45 and, as is depicted in FIG. 2 and in FIG. 4, are held in place and supported by open ended retaining shelf or support 25 .
- the entirety of the seabed mat 70 is fully supported by the seabed mat placement device 10 of the present invention through the use of a plurality of support straps 57 which engage a matching plurality of support line loops 72 .
- the plurality of support straps 57 are supported directly on the placement device 10 through displaceable supporting pins 44 such that upon rotation of actuation lever 36 , displaceable supporting pins 44 are removed from the retaining support 25 and the support straps 57 fall through the loops 72 and the entirety of the seabed mat may be displaced and positioned directly below the location of the placement device 10 .
- the placement device 10 of the present invention may be supported by a plurality of support chains 50 which may depend below a crane or other supporting device.
- the support chains 50 may be directly connected to a plurality of anchors 51 evenly placed on the device 10 of the present invention so that the entire device may be raised and lowered by the support chains 50 and sufficient structural support should be provided such that the entire device may be lifted with a mat 70 retained there below.
- support chains 50 may position the placement device wherever the mat need be located and if such placement is required under water, an additional chain or other attachment device may be provided which is attached to actuation lever 36 such that upon upward force of the attachment chain, actuation lever 36 will cause rotation of the actuation shaft 30 thereby releasing the displaceable supporting pins 44 from the retaining shelf or support 25 .
- the displacement of the mat may be effectuated in a short span of time by a single rotation force on actuation lever 36 .
- rotation of actuation lever 36 will cause a corresponding rotation in actuation shaft 30 .
- Shaft 30 is rotatably retained along the top of the placement device 10 by a plurality of collars 32 which allow rotation of the actuation shaft 30 therein.
- the actuation shaft 30 is supported above the first and second support beams 20 and 21 which have a plurality of cross support members 27 extending there between. Located adjacent each of the first and second support beams 20 and 21 are a first and second release shaft 41 and 40 which are rotatably connected to the actuation shaft 30 .
- the first and second release shafts 40 and 41 are rotateably retained on the first and second support beams 20 and 21 by a plurality of support collars 42 which anchor the release shafts but which allow rotatable movement therein.
- Each of the first and second release shafts 40 and 41 are rotatably attached to the actuation shaft by a plurality of driver arms 34 which are pivotally connected to the actuation shaft 30 .
- rotation of the actuation shaft 30 causes similar rotation in each of the first and second release shafts 40 and 41 .
- Different size shafts may be utilized for the actuation shaft or for the release shafts which will cause varying translation of rotation between each other.
- a larger actuation shaft may be supplied thereby causing significantly more rotational displacement of each of the release shafts depicted.
- the release shafts 40 and 41 are rotatably engaged to the actuation shaft 30 by the plurality of driver arms 34 .
- Each of the driver arms are fixed to the actuation shaft 30 at pivot points 35 .
- the driver arms 34 which connect the second release shaft 40 are pivotally attached to the actuation shaft 30 along a 180° displacement point to the pivot point of the attachment of the driver arms which rotatably engage the actuation shaft 30 to first release shaft 41 .
- rotation of the actuation shaft 30 will cause opposite rotation of each of the release shafts thereby causing displaceable supporting pins 44 , found on either side of the placement device 10 , to simultaneously be removed from the open ended retaining shelf 25 found on first and second support beams 20 and 21 .
- the seabed mat 70 is fully supported by the placement device 10 of the present invention and rotation of lever 36 upward from its position as is depicted in FIG. 2 will cause clockwise rotation of first release shaft 41 and counter-clockwise rotation of second release shaft 40 .
- the entirety of the seabed mat 70 may be released in consistent fashion with all of the displaceable supporting pins 44 being removed from the retaining shelves 25 in direct fashion thereby providing for accurate placement of the mat 70 upon release from the placement device 10 .
- the entire system is much more stable and more accurate placement of the mat when release occurs.
- one benefit of the seabed mat placement device 10 of the present invention is that the seabed mat 70 may be releaseably attached to the placement device 10 along the outer sides of the first and second support beams 20 and 21 .
- a worker who must affix the support straps to the placement device 10 will not be required to stand on the placement device, which may be hazardous, and may merely stand on the periphery of the device while affixing the support straps 57 to the loops formed by block support lines 72 .
- the placement device 10 of the present invention has first and second support beams 20 and 21 .
- end plates 24 and 23 which provide a flat planar surface for attachment in end to end relationship of a plurality of the placement devices.
- the placement device 10 of the present invention may be adhered together in end to end relationship by abutting end plates 23 and 24 to opposing end plates 23 and 24 on a second placement device.
- actuation shaft 30 may be of significant length such that the end which is opposite to actuation lever 36 may have a connection bar 49 which may additionally be attached to the actuation lever of the second placement device.
- connection bar 49 would be directly but removeably attached to the actuation lever of the adjacent placement device.
- the actuation lever 36 may be locked in the downward position such that the seabed mat 70 will not be accidentally released.
- this locking of the actuation lever 36 may be effectuated by a locking sleeve 62 a and 62 b between which the end of actuation lever is placed.
- actuation lever may have a locking aperture 39 which may receive a locking pin 61 extending through both of the locking sleeves 62 a and 62 b and thereby preventing upward rotation of the actuation lever 36 .
- a latch 63 which is rotatable about latch pin 64 may also provide a secondary safety mechanism which prevents upward movement of the lever 36 .
- Latch 63 may therefore have an outwardly extending tongue portion 66 which mates with a locking sleeve tongue portion 65 both of which may be locked together by an additional locking pin or locking device, not shown, by providing an aperture through both tongues 65 and 26 .
- the seabed mat placement device 10 of the present invention has support beams and cross support members which may preferably be made of steel or similar material. It may also be preferable that the support beams and cross support members are hollow so as to reduce the weight of the placement device. Further, the actuation shaft and release shafts must be of sturdy design but may also be hollow so as to reduce the weight.
- the support collars which allow rotateable movement of the actuation shaft or the release shafts may be greased appropriately so that rotational movement of all of these shafts is readily done. All of the support brackets and retaining pins utilized to support the seabed mat may be welded to the side surface of the first and second support beams 20 and 21 . Additionally, since a significant amount of weight will need to be supported by the anchors 51 , these anchor members 51 should be welded to a rigid and structurally supportive area of the first and second support beams 20 and 21 .
- FIG. 6 Another benefit of the device of the present invention is shown in FIG. 6 wherein a support and release frame 100 is comprised of a first frame 102 and a second frame 104 placed in end to end abutting relationship.
- the frame 100 had a junction point 110 wherein the first support beam 120 of first frame 102 is adjoined to first support beam 123 of second frame 104 .
- second support beam 121 is adjoined to second support beam 122 of second frame 104 so that a double lifting and placement device is created with the ability to support two end to end concrete mats.
- rotational force applied to lever 136 drives actuation shaft 130 , which is joined to the actuation shaft of the second frame 104 at joint 108 .
- Accurate placement and release of two mats may then be accomplished since the force of the actuation shaft 130 extends along the entire support and release frame 100 thereby driving the driver arms along the entirety of the frame as well as the release shafts for each adjacent frame, which as can be seen need not be connected.
- the entirety of the frame 100 may be supported by chains 150 and placed where needed in order to accurately release two or more mats.
